When the announcement was made regarding the issue, the Privy Council called for submissions over a four-week period from lawyers on whether a retrial should be held.

Pora was convicted of murdering Susan Burdett, a 39-year-old who was bludgeoned to death with a softball bat in her Papatoetoe home in 1992.

Mr Pora was found guilty of Ms Burdett's murder in 1994, aged only 17. In 1999, his first conviction was quashed after DNA evidence from semen found at the murder scene, linked to serial rapist Malcolm Rewa, who was eventually convicted of the rape of 27 women, including Ms Burdett, but not for her murder.

In 2000, Pora was again found guilty of Ms Burdett's murder in a retrial but his appeal was dismissed.

Pora has always maintained his innocence and was released on parole in April last year.
